A high current electron beam ion trap for fast charge breeding — •Thomas Baumann, José Crespo López-Urrutia, and Joachim Ullrich — Max-Planck-Institut für Kernphysik, Heidelberg, Germany

A new high current electron beam ion trap (EBIT) is constructed at the MPIK Heidelberg. This machine will utilize an up to 5 A electron beam, which is strongly confined by a 7 T magnetic field, to produce and trap highly charged ions from almost any stable element. The electron beam energy will be adjustable between 100 eV and up to 200 keV, while the extremely high current density within the trap region will allow for fast charge breeding, which enables this EBIT to produce He-, H-like or bare ions of heavy elements in hundreds of ms. These ions can be studied by experiments using high resolution spectrometers in the visible, soft x-ray and x-ray spectral range. Furthermore the ions will be extracted out of the EBIT into other experiments like ion-surface interaction measurements, a reaction microscope to study collision dynamics or a penning trap for high precision mass spectrometry.
